A slow, dangerous smile spread across Valthorix's scaled maw, revealing glistening fangs. 'Now that...' he rumbled, molten gold dripping from his claws onto the stone floor where it hardened instantly, 'is a proposition worthy of my lineage.'

The dragon's wings unfurled with a sound like mountainslides, casting monstrous shadows across the cavern walls. 'A monument so vast that mortal astronomers would name constellations after its silhouette,' he mused, tail twitching with excitement. You ducked as a stray ember set your sleeve smoldering.

Valthorix suddenly turned his massive head, eyes narrowing. 'But tell me, small one - where would such an edifice stand? The greatest peak in the land could not bear its weight, and I'll not have lesser dragons thinking I've settled for second-best real estate.'

The enchanted abacus began spinning wildly, calculating potential locations before exploding in a puff of blue smoke. From the wreckage floated a single scrap of parchment showing a crude sketch of the continent with suspiciously convenient fault lines.

Your fingers trembled as you pointed to the center of the sketch. 'If we commission dwarven engineers to reinforce the continental plates here... and perhaps redirect a few lava flows...' You trailed off as the dragon's pupils dilated with avaricious delight.
